SPECIFICATION forming part of Ltterslatent 'No. 734,447, dated July 21,1903. Application filed Novemberlfl. -1902.- Serial lilo-131,823.(Remodel) To all whom it may concern:

Be it known that I, HARRY J .VALENTINE, a citizen of the United Statesof America, anda resident of Cleveland, Ouyahoga county, in the State ofOhio, have-invented certain new and useful Improvements inSpring-Hinges, of which the following is a specification.

This invention relates tospring-hinges of the class, whether single ordouble, which are applied to the door and door-frame unset, but whichare so constructed that after screwing them in position their springsmay be tightened up and placed under tension. Y

The objects of the present invention. are, first, to so constructthetubularpintle'on which the hinge-knuckles turn that theopcrating-spring may be readily and conveniently set from anintermediate point on the hinge; second, to provide ample and smoothantifriction-bearings for the knuckles, and,"

,third, to provide the hinge with a checking hinge which will beefflcient in action and which overcomes some of the defects of those nowon the market.

My invention consists of certain features of construction andcombinations of parts, to be hereinafter described in detail and thenpointed out in the claims.-

In the accompanying drawings, Figurel' is a side elevation ofa hingemade in accord ance with the present invention, the leaves being shownclosed. Fig.'2 is a plan view with the leaves closed and the upper tip'or knob and its rivet removed. Fig. 3 is a detail of the npperpart ofthe hinge, partly broken away to disclose the parts inside the tip andtubular pintle. Fig. 4 is a transverse section through the base of thetip and intorior parts with the leaves in plan and opened out fully.Fig. 5 is a longitudi-nal section of the central portions of'the-hinge,the leaves Fig. 6 is a detail perspective view of the cup or disk towhich the upper end of the operatingspring is applied. Fig. 7 is adetailperspective view of the cup or disk to which the upper end of thecheck-spring is applied. Fig.

.8 is'a detail'perspective View of the upper sec tionof the tubularpintle, and Fig. 9 is a detail perspective view of one of the-Washersbetween the knuckles.

While in the drawings the invention is ,shownas applied to a singlehinge, it is to be understood that the invention is equally applicableto a double hinge.

The'hinge-leaves AB are provided with knuckles ab, respectively, throughwhich the tubular pintle composed of sections 0 0' passes. Preferablythe lower section 0 is provided with a capstan-ring D, slipped over itand secured on it by a set-screw d and located between the'two middleknuckles of the hinge shown, which knuckles hear at their adjacent edgesupon the said ring. ring has a suitable number of holes 01 forreceivinga locking-pin 61 which is inserted in position in one of themand is engaged by the leaf B in opening the hinge for straining the mainor operating spring to be described. The upper section 0 of the tubularpintle is secured to upper knuckle a of leaf A by a set screw or screws0, and the lower section 0 is free to be adjusted in the lower knuckles.Set-screw 0 screws also into the flange of a cup or flanged disk E,which is located in the upper end of tubular section 0. An axial openinge, for the purpose to be stated later, is formed in the cup E, and aholee is located in the disk at one sidethereof to receive the This'upwardlybent upper endf of the helical main or operating spring F, thediameter of which is nearly that of the inside of the tubular pintle. Adownturned lower end f on the spring F is engaged in a side hole g, lo-.cated in an inverted cup or flanged disk G, secured in the lower end ofthe tubular section 0 by set screw or screws 0. The spring F simplyengages in the holes '6 g at: both ends and requires no other fastening;To tighten the spring, a short lever or nail i'sinserted into one of;the holes in the capstanring D and the locking-pin (1 set behind leaf B,the lever being reinserted, the ring being turned, and the locking-pinreset until a sufficient tension is placed on the spring. The method ofdoing this is well known.

The lower knob or tip H is secured to the pintle-section C by thedescribed set-screw c, and the upper knob II is placed onto the upperend of the upper pintle-section C, it being secured in position in themanner to be described later.

Between the knuckles a b of the hingeleaves are suitable bearings formedby preferably dished collars or washers I I, which are only slightlylarger in internal diameter than the tubular pintle and which arearranged in pairs, placed with their concaved faces together, preferablyto form raceways for antifriction-balls j. These collars I I areprovided with outturned key-lugs or projections 1;, which interlock withcorresponding recesses 71 in the knuckles, so that one of the collars ofone pair between adjacent knuckles is locked or anchored to one knuckleand the other collar is fixed to the other knuckle. The outer contactedges I of the collars preferably bear upon each other and take up moreor less wear. In this event they are made of case-hardened steel toserve as wearcollars, the use of the autifrictiomballs then being amatter of choice only. The balls bear on the outer surface of thetubular pintle, so that rolling antifriction-stnfaces are not onlyprovided between the knuckles, but also between the knuckles and pintle.

The invention further resides in means for checking or retarding theaction of the operating-spring just before the door closes, therebypreventing slamming of the door. To this end a helical check-spring K ispreferably located in the pintle within and inclosed by theoperating-spring F, and as it is somewhat less in diameter and thesprings are suitably fixed apart the springs do not interfere by rubbingon each other. The lower end of the checkspring K is bent downwardly atk and is engaged in a hole g in the lower cup or disk Gr, while theupper coils of the check-spring pass through the enlarged centralopening e in cup or disk E. The upwardly-bent upper end of thecheck-spring is engaged in a hole Z in an inverted cup or flanged diskL, which is located in the upper end of the pintle-section C and mayturn therein. The rim of the cup or flange of disk L is presenteddownwardly to abut against and turn on the upwardlypresented rim of thecup or flange of the disk E. A series of holes Z is formed in the flangeof cup or disk L, and opposite these holes the pintle-section O has ashort transverse slot 8, which is also located opposite a series ofholes m in the rim of the upper knob H, the said holes Z registeringwith the holes m, so that a check or tension pin on may be inserted inthe same. This pin m puts tension on the check-spring reverse to thetension of the operating-spring, to which end it is adapted to beimpinged on by the inner side of the leaf B. The tension on thecheck-spring is obtained upon tightening the same up by insorting alever or nail in the holes Z m and turning the knob H and cup or disk Luntil a light tension is imparted to the said spring,

when the check-pinm is inserted in other of said holes and abuts againstthat end of the slot m adjacent the leaf B when the leaves A B areopened. The initial tension is such that when the leaves are fullyopened the pin m will be brought, preferably, to position shown in Fig.4:, and when the leaf B closes toward and abuts on said pin the latteracts as a check to the quick action of the operating-spring and preventsslamming of the door, acting contrariwise to the operating-spring.

For holding the knob H and the cup or disk L in place against accidentalseparation from the hinge the same are preferably connected by a pin orrivet 1', which passes through a transverse slots at that side ofpintle-section O which is opposite the slots. The pin or rivet 1*preferably forms a stop to limit the tension placed on the check-spring.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is-

1. In aspring-hinge, the combination of the leaves and knuckles, atubular pintle inserted through the knuckles, and composed of sections,one of which is attached to one leaf and the other of which is rotatablerelatively thereto, a capstan-ring secured on the rotary section andlocated approximately midway of the hinge, the division between the twosections being located to one side of the said ring, and means forsetting the rotary section in adjusted position against one of theleaves, and an operating-spring in and attached to said rotary sectionto close the leaves, substantially as described.

2. In a spring-hinge, the combination of the leaves and knuckles,a-tubnlar pintle inserted through the knuckles, and an operatingspringand paired collars arranged between adjacent knuckles of the respectiveleaves for taking up wear by the contact of their faces with each other,one collar of each pair being secured to one adjacent knuckle and theother of the pair being secured to the other adjacent knuckle,substantially as set forth.

3. In a spring-hinge, the combination of the leaves and recessedknuckles, a tubular pintle inserted through the knuckles, anoperating-sprin g, and collars between the knuckles, one provided with alug inserted in the re cess of one adjacent knuckle and the other with alug inserted in the recess of the other adjacent knuckle, substantiallyas set forth.

4. Inaspring-hinge, the combination of the leaves, an operating or mainspring, and a check-sprin g opposing the action of the operating-spring,substantially as set forth.

5. In a spring-hinge, the combination of the leaves, anoperating-spring, and a checkspring of less diameter than'and locatedwithin the operating-spring, said check-spring serving to check theclosing actionof the operating-spring when the leaves are about toclose, substantially as set forth.

6. In aspring-hinge, the combination of the leaves, theoperating-spring, a check-spring inclosed within the operating-spring,one end of each spring being fast at one end of the hinge and the otherend of each spring being adapted for being tightened, means fortightening up the operating-spring, and means for tightening up'thecheck spring, said check- -spring acting against the operating-springpintle at each end, said pintle being sectioned between the disks, andan operating-spring attached at one end to one disk and at the other endto the other disk, a check-spring secured to the fixing-disk of theoperatingspring at one end, the other end of the checkspring passingthrough an openingtin the other disk, and means for tightening up or adjusting, the tension of the check-spring, substantially as set forth.

9. In a spring-hinge, the combination of the leaves,theoperating-spring, and a check-pin arranged between the leaves so as -tobe out of contact with the leaves when the hinge is opened and tocontact with the closing leaf when the same is closing, tocheck theaction of the operating-spring, substantially asset forth.

10. In a spring-hinge, the combination of the leaves, theoperating'spring, a checkspring, a pin for acting on the spring andagainst which one of the leaves abuts, and means for limiting themovement of the pin to a portion of the extent of movement of theabutting leaf.
